The top portion 1 a includes a top board 14 having at least one upper through-hole 11. The bottom portion 1 b includes at least one lower through-hole 12. The at least one upper through-hole 11 and the at least one lower through-hole 12 intercommunicate with the hollow portion H. Thus, indoor hot air can be discharged via the at least one vent A, the hollow portion H and the at least one upper through-hole 11. Furthermore, when water enters the hollow portion H via the at least one upper through-hole 11, the water can be discharged to the wavy plate 3 via the at least one lower through-hole 12. The at least one upper through-hole 11 is located on a first side of the top board 14. Furthermore, a net 13 is mounted on top of the at least one upper through-hole 11 to prevent alien objects from falling into the hollow portion H.

The top board 14 includes a stop portion 141 and two protruding members 142. An end of the at least one shielding plate 2 abuts the stop portion 141. The two protruding members 142 are located on a second side of the stop portion 141. A water channel 15 is formed between the two protruding members 142 and includes at least one drain hole 151 extending from an upper surface through a lower surface of the top board 14 and intercommunicating with the hollow portion H, such that water can enter the hollow portion H via the at least one drain hole 151 and can be discharged to the wavy plate 3 via the at least one lower through-hole 12. An end of the at least one shielding plate 2 rests on the two protruding members 142 of one of the two frames 1, such that the at least one drain hole 151 is not blocked by the at least one shielding plate 2. Each of the two protruding members 142 can be comprised of a plurality of protrusions, and a water passageway is formed between two adjacent protrusions. In an alternative example, each of the two protruding members 142 is an elongated member having at least one through-hole 152. Thus, water falling through the gap between the at least one shielding plate 2 and the stop portion 141 can enter the hollow portion H via the at least one drain hole 151. Furthermore, the bottom portion 1 b includes a side having a first insertion groove 16 and an extension plate 161.

Furthermore, an inner wall of the frame 1 delimiting the hollow portion H includes a plurality of second insertion grooves 17. A plurality of baffles 18 is coupled with the plurality of second insertion grooves 17 and is alternately disposed, such that a zigzag passageway is formed in the hollow portion H. Thus, the indoor hot air can be discharged via the at least on upper through-hole 11. Furthermore, the zigzag passageway prevents water from splashing into the air passage 30 via the at least one through-hole 11. The plurality of baffles 18 can include a plurality of holes 19 to rapidly discharge a portion of the hot air.

The at least one shielding plate 2 can be any conventional plates, including but not limited to metal plates, glass plates, transparent plates, etc. Each of the two ends of the at least one shielding plate 2 is placed on the two protruding members 142 of one of the two frames 1. Furthermore, a gap between each of the two ends of the at least one shielding plate 2 and the stop portion 141 is sealed by a sealing glue S such as epoxy resin, preventing water from leaking into the inside of a house.

With reference to FIG. 3, in this embodiment, a bottom board 31 includes an engaging portion 32 engaged with the first insertion groove 16 of the at least one frame 1. The bottom board 31 is fixed to a rib 34 on the wavy plate 3 by a plurality of fasteners 33. Thus, the at least one frame 1 can be securely fixed on the wavy plate 3.

With reference to FIGS. 2 and 4, the improved structure of the ventilated roof further includes a plurality of connecting beams 4 connected between the two frames 1. Each of two ends of each of the plurality of connecting beams 4 has a connecting portion 41 connected to one of the two frames 1. In this embodiment, the connecting portion 41 is a positioning hole, and fasteners 42 are used to fix the two ends of each of the plurality of connecting beams 4 to the two frames 1. Furthermore, each of the plurality of connecting beams 4 includes a top portion having at least two ridges 43 and a vertical plate 46. At least one guiding groove 44 is defined between the at least two ridges 43 and a corresponding one of the plurality of connecting beams 4 having the at least two ridges 43. A top of each of the at least two ridges 43 is flush with a top of each of the two protruding members 142. In this embodiment, the top portion of each of the plurality of connecting beams 4 has two guiding grooves 44. Each of the two guiding grooves 44 is aligned with one of the through-holes 152. The height of the vertical plate 46 is higher than a height of the at least two ridges 43. A protective cover 45 is coupled to the vertical plate 46. When the connecting portions 41 at two ends of each of the plurality of connecting beams 4 are connected to the two frames 1, an edge of the at least one shielding plate 2 rests on the at least two ridges 43, and a side of the at least one shielding plate 2 abuts a side of the protective cover 45. A gap between the side of the at least one shielding plate 2 and the plurality of connecting beams 4 can be sealed by a sealing glue S, such as epoxy resin, preventing water from leaking into the inside of the house via the gap. Furthermore, each of the two guiding grooves 44 is aligned with a corresponding through-hole 152. Thus, when the sealing glue S has aged and deteriorated after long-term use and, thus, cannot seal the gap, even if water leaks into the guiding grooves 44, the water is discharged through the at least one drain hole 151, flows through the hollow portion H of the frame 1, and is discharged to the wavy plate 3 via the at least one lower through-hole 12.

With reference to FIGS. 2 and 4, the improved structure of the ventilated roof further includes a sideboard 5 fixed by a plurality of fasteners 51 to two ends of the at least one frame 1. The sideboard 5 seals two ends of an air passage 30 formed by the at least one frame 1 and the at least one shielding plate 2, providing a better appearance.

With reference to FIG. 2, in this embodiment, the ventilated roof is comprised of two frames 1 and at least one shielding plate 2. For each of the two frames 1, an engaging portion 32 of a bottom board 31 engages with the first insertion groove 16 of the frame 1. The bottom boards 31 are fixed to the ribs 34 on the wavy plate 3 by a plurality of fasteners 33. Thus, the frames 1 can be securely fixed on the wavy plate 3. Each of the two ends of the at least one shielding plate 2 is placed on the two protruding members 142 of one of the two frames 1. Furthermore, the gap between each of the two ends of the at least one shielding plate 2 and the two frames 1 is sealed by the sealing glue S such as epoxy resin. Thus, the two frames 1 and the at least one shielding plate 2 form an air passage 30. As a result, the indoor hot air can pass through the at least one vent A into the hollow portion H of each of the two frames 1 and can be discharged via the upper through-holes 11 of the two frames 1. The nets 13 on top of the upper through-holes 11 of the two frames 1 prevent alien objects from falling into the hollow portions H. Water falling through the upper through-holes 11 into the hollow portions H can be discharged to the wavy plate 3 via the lower through-holes 12 and can fall downward along the channels between the ribs 33 of the wavy plate 3 without the risks of entering the inside of the house. Thus, although the sealing glue S has aged and deteriorated due to long-term use and, thus, fails to seal the gap, the water leaking downward through the gap still can enter the hollow portion H via the at least one drain hole 151 and can be discharged to the wavy plate 3 via the at least one lower hole 12, such that water can fall downward via the channels between the ribs 34 of the wavy plate 3, preventing water from entering the inside of the house.

FIGS. 5 and 6 show an improved structure of a ventilated roof of a second embodiment according to the present invention. In a case that the improved structure of the ventilated roof is used on a roof ridge using two wavy plates 3 that incline downward. An edge of the extension plate 161 of each of the two frames 1 abut the coupling portion 61 at a top portion of a decorative plate 6. Each decorative plate 6 is arcuate and includes a plurality of notches 62 matched with ribs 34 on the corresponding wavy plate 3. Each decorative plate 6 can be fixed to the corresponding wavy plate 3 by a plurality of fasteners 63. Then, each frame 1 is fixed by fasteners 162 to the corresponding decorative plate 6 and the corresponding wavy plate 3. Thus, after the frames 1 are coupled to the wavy plates 3, the bottom surface of each arcuate decorative plate 6 abuts the ribs 34 of the corresponding wavy plate 3 and the channels between the ribs 34. As a result, the frames 1 and the wavy plates 3 have a better appearance after coupling while preventing water from entering the inside of the house via the channels of the wavy plates 3.

Furthermore, a protective member 7 is mounted between the two frames 1. The protective member 7 can be a protective net or a protective board. A plurality of supporting members 71 is disposed on each of an inner face of each of the two frames 1, with the inner faces of the two frames 1 facing each other. The plurality of supporting members 71 is fixed to the two frames 1 and is coupled to the protective member 7. Thus, when a worker is proceeding with installation or maintenance of the ventilated roof, the protective member 7 prevents falling of installation tools, alien objects, or the worker.

In view of the foregoing, in the improved structure of the ventilated roof, since the top portion 1 a of the at least one frame 1 includes at least one drain hole 151 extending through the top portion 1 a and intercommunicating with the hollow portion H, such that water enters the hollow portion H via the at least one drain hole 151 and is then discharged to the wavy plate 3 via the at least one lower through-hole 12. Thus, water flows downward along the channels between the ribs 34 of the wavy plate 3, preventing water from entering the inside of the house. Furthermore, the ventilated roof can include the protective member 7 to prevent falling of installation tools, alien objects, or the worker when the worker is proceeding with installation or maintenance.
